Guidance on a Conflicted Engagement

Your fiancé is very good; you have been engaged for 4 years and are now about to get married. He takes good care of you. You found out about his fetish tendency. First of all, tell me, since he is not your mahram (a male relative whom you cannot marry, making him a stranger/non-related man), how did you get so close that you found out about such a private thing? You are the reason why these tendencies of his thrived; some dissatisfaction on his part is also involved. You gave him certain vibes that made him expect this from you. You didn't satisfy him, but you were there to adore him, so you are confusing him greatly. But he can also be at fault, as you said he's sexually immature. Look at this, these things will turn into problems, and men often believe that 'The room is ours, the wife is just there to comply.' Just don't take the risk. Instead, open up and talk to your father or brother. Tell them everything, and let them speak sincerely with his family. These issues require treatment. You can't leave him since you are engaged for 4 years. You can consider leaving him only if he doesn't want medical assistance or resists it.
